5 years ago I decided to write my own engine in C++. I am so excited to say that I have just released my first game based on that technology, I am so proud to be able to paste this link to a game I coded, coloured, recorded and deployed myself https://yesindiedee.itch.io/sildetosurvive
Full release is now available, there is also a free demo so you can give it a go.
If you are interested in how the concept was created there is also a little behind the scenes development video on the game page.
I hope you you have fun!
